Metal polishing is a finishing method that uses an abrasive material to smoothen surfaces. When polished, the surfaces of metallic objects are freed of defects and become more reflective and shinier, enhancing their appearance.
Metal polishing can be complemented by buffing, a less harsh method that results in a brighter finish. Certain type of surface finishes such as mirror finish can be achieved by applying chemical during surface polishing. (This only applies to stainless steel sheet surface polishing).
Another type of surface polishing is cold drawing, which is commonly used on steel bars or other various special-shaped bars, starting with circular and hexagonal shapes. The processes are as below:-
Cold drawn finished steel bar is used in various fields, for example, automobile and manufacturing machine's parts etc.
